Ultrasonic welding technology is used in film bagging machine,which the heat fuses transfer film together. Exposed to ultrasonic genereating box, the fim starts to vibrate. Two sides of the film starts to create friction and the heat friction reaches the melting point of the film. therfore , the film layers are being welded together.

To run the machine electrical power and compressed air is required. As shown in the picture the film is loaded in to a air expansion shaft. Then the film is folded in U shape and connected together in to the welding zone,By turning on the ultrasonic, and pressing the sonotrode onto the film , the welding is done.The profiles are placed on the table and loaded from oneside,and are covered with film,passed the welding zone and unloaded from the other table by operators.

The film wrapped profiles, then are changed one by one in sucking heads in heat transfer machine, when air between the film and profile surface is completely removed. then they are placed in to the oven to complete decoration process.
